What 蚒 means
It is a Chinese written variant linked to red.
Chinese character dictionaries list 蚒 as a variant of 彤, whose older meaning describes applying red decoration. They also link 蚒 with 赨, another form associated with the red sense.
Where does 蚒 come from?
Records of 彤 show the graph in bronze inscriptions from the late Western Zhou, manuscripts from the ancient state of Chu, and the Shuowen, an early Chinese dictionary.
These examples document the related graph; they do not date the exact written form 蚒.
What if someone sends 蚒 alone?
Treat it as a text or dialect clue until you know the source.
A Chinese dictionary entry gives it a separate Cantonese reading and a sense for an edible snake or lizard. Ask which language or text it came from before assigning the animal meaning to a standalone message.
If it appears as a box, the font or app cannot display 蚒; that changes how it looks, not which character the text contains.
Specialist, historical, or dialectal; identify the source language if readers may not know the character.
Do not assume the animal sense applies to every standalone 蚒.

1Why does 蚒 show as a box on some devices?
Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
